gnoMint 1.6.1 "Tempered Anvil"

Multi-platform CI and Windows installer release.

• Multi-platform CI via GitHub Actions. Automated builds and tests on Fedora (latest), Arch Linux (rolling), macOS (Homebrew), and Windows (MSYS2/MinGW64) on every push and pull request.

• Windows MSI installer built with WiX v5. Bundles both gnomint and gnomint-cli with all required MinGW runtime DLLs, GTK 4 theme and icons, GLib schemas, translations, and UI files. Includes Start Menu shortcuts, .gnomint file association, and PATH entry for gnomint-cli. Uploaded as a CI artifact on every build.

• FIX: Windows portability — replaced POSIX arpa/inet.h with winsock2.h and POSIX regex.h with GLib GRegex for MinGW compatibility.

• FIX: Windows relocatable install — PACKAGE_DATA_DIR is now resolved at runtime relative to the executable location via g_win32_get_package_installation_directory_of_module(), so the MSI-installed binary finds its data files regardless of install path.

• FIX: GSettings on Windows — uses the keyfile backend so preferences persist without a D-Bus session or system registry.

• TESTS: All CLI shell tests now pass on MSYS2/MinGW64 with proper POSIX-to-Windows path conversion (cygpath) and MSYS2 argument mangling suppression (MSYS2_ARG_CONV_EXCL) for openssl commands.

Database-compatible with 1.4.0 — no migration needed.
